`Be it known thatI, Wim-mim HARTMANN,"

a subject of the German Emperor, residing at, Oiienbach-on-the-Main, Germany, `have invented certain new and useful Improvements in Ash-Ejecting Mechanism, of which the following is aspecication.

The removal of hot ashes, clinkers and the like waste material in large furnace installations,` for examplemarineboiler furnaces, is,

as is well known, extremely inconvenient `by directly carried od by means of air` under suction, not onlynwithout raising dust, `but also with water cooling or slaking.

The invention is characterized by the feature that the conveyer pipe of the ash eject# ing mechanism, `which operates the removal or conveyance of the material, passes the latter directly into a second pipe, in which water or the like is permanently maintained at a given level by suction action, which water is introduced from the outside, either from a separate tank, or, in the case of ships,

directly from overboard, in such a way that the hot material is passed directly into the water and is discharged through it while the suction air passes into'the freed from dust and purified.

A form of construction of the invention is illustrated in the accompanying drawing.

This figure is a diagrammatic view of a container such as a ships hull S on the deck D of which, or in any othersuitable place, the suction chamber a is erected. This suction chamberf isV kept under permanent vacuum through a pipe d. in known manner e' by means of an air pumperected in any suitable place on the ship, and which is not shown in the drawing. A discharge pipe e leads down from the chamber a and its lower end opens through the ships hull into the water outside, while its upper end connects with the suction chamber a by means of a nozzle e. The upper partof the pipe e is widened and so shaped as to form a curved chamber e2. A movable pipe la leads upwardly from the interior of the ship pump entirely Asn-nancrine Mn'eninistr e specification of Letters raient.

through` the deck and extends through the suction chamber a, in" which it is curved first downwardly, then againupwardly, and pro-` )ects into the nozzle e which, as shown, is of larger diameter than that of the conveyer pipe c. As by the vacuum `in the chamber `a water isdrawnup from overboard through the pipe le and maintained at such a height that it surrounds Vthe mouth of the conveyer pipe lc. lThe entire `material is raised through the conveyer pipe 7c and is ejected from said pipe into the chamber e2 through the slaking water. The slaked material ejected from the pipe c then falls into the water of the pipe e and sinks therethrough into the sea, while the air passing through the water surrounding the mouth of the plpec is drawn into the suction chamber a e and thus reaches in a purified state the pump through the pipe d. The suction pipe c ter- `minates at its lower end directly in front of the boiler furnace, `and is made movable sothat ashes, slag and the like can be drawn directly from the front of the furnaces and conveyed overboard without any annoyance of dust, gas or heat.

The operation is as follows: The chamber a being held constantly at a vacuum, the ashes, clinkers, etc. will be drawn through the pipe v and owing to the great velocity with which the air passes through the latter, will be thrust through the nozzle c into the chamber e2, as indicated by the dotted arrow. Simultaneously in accordance with the vacuum created in the chamber a water will rise into the pipe e to such a level as to surround the mouth of the pipe 7c. The material conveyed through the pipe 7c will be ejected into the chamber e2 through the water surrounding the mouth of the pipe 7c, whereby it will be cooled, while the air traveling together with the material will in passing through the water become purified.

water supply and formed with a wider part communicating with the said chamber and into which said first pipe projects, both said pipes being exposed to the suction action created in slictionchairiher to such a 1ere/ias' to surroundthe mouth of` the said conveyer pipe, so that Vthemateriai y conveyed from the container by suction is thrllSt, through the Waterf.surrounding thev mouth of the conveyer pipe into the discharge pipe While the air traveling-Withthe` material is purified. i
